Geocaching

If you're not familiar with Geocaching, let me elucidate. Geocaching is a game where people hide caches (containers with various objects, including a logbook), post the GPS coordinates to a website, and other people try to find the cache. Now, there are a lot of variations to the game, such as encrypting the clues to the cache, having staged caches where each stage gets you one clue closer to the final cache, or "virtual" caches where the final destination is a monument or marker of some sort. (For additional information, go to geocaching.com) Bottom line, geocaching is a fun activity and I highly recommend it.
